. I 01 MOLINE, ILLINOIS, A CORPORATION OF ILLINOIS URE SPREADER Original applicationfiled March 21, 1925,-Seria1 No. 17,321. Patent No. 1,724,379, dated August 13, 1929. Divided and this application filed July 10, 1929. Serial No. 377,249.

My invention relates to manure spreaders of the well-known type comprising a vehicle body mounted on front and rear wheels, a traction driven rear axle on which the rear wheelsare mounted, and by the forward rotation-of which it orthe driving parts mounted thereon are driven, a rotary beater which is preferably mounted on the rear axle, and a traveling apron or conveyor, the upper course of which in its intermittent movement conveys the contents of the vehicle rearwardly to gradually feed the same to the beater.

,A manure spreader of this general type is shown and described in my prior Letters Patent No. 1,7 24,379, dated August 18, 1929, the present applicationbeing a division. of said patent.

The subject-matter of the present application pertains to the means for'regulating the rate of feed of the load to the distributing mechanism, having as its object to provide 7 improved means of such character that the adjustment of therate of feed maybe made not only when the distributing mechanism is in operation, but also when it is at rest,

and without imposing .on the operator the burden of moving the loadin making such adjustment, which object is accomplished as a illustrated in the drawings and as herein- T 30 after described. What I regard, as new is setforth in the claims.

In the accompanying drawings,' t Fig. 1 is'a side elevation of a manure spreader embodying my improvements;

Fig. .2 is a plan view of one side of the rear portion of the spreader, some parts be ing broken away; t Fig. 3 is a side elevation of the rear por- E tion of the spreader, illustrating the mechanism; for" actuating the feeding apron and for regulating the rate of feed;

Fig. 4 is a detail, being a part al side eleva ;tion of the front portion of the spreader showing themanually operated lever for adjusting the rate of feed and Figs. 5 and 6 are details, showing different positions of the feed regulating mechanism.

Referring to the drawings,10 indicates ;-the usual vehicle bodyl'and 11 the side sills thereof, 12 the front, wheels and 13 the rear" 1 should be understood that while my improved driving mechanism is well adapted for use in wheels. The rear wheels are mounted on a rear axle 14 journaled on the vehicle body in any suitable way, but preferably in boxes 15 carried by brackets 16 secured to the side sills 11. It will be understood that the rear wheels 13 are connected with the rear axle 14 by means of the usual ratchet connections contained in housings 17, so that forward rotation of the wheels will drive the rear axle, but said wheels will be free to rotate in the opposite direction independently of the axle, as is necessary in rounding curves.

Loosely mounted on the rear axle 14 is a 'main beater 18, of any approved design, preferably consisting of spiders or heads 19,

auxiliary beater 27, comprising heads 28 mounted on the end portions of the countershaft 26 and connected by cross-bars 29 provided with radial fingers 30, see Fig. 2. The heads 28 are suitably keyed to the countershaft so that they rotate therewith. Preferably the bearings 25 areformed in brackets 31 suitably secured to the side boards of the vehicle body.

The countershaft 26 is somewhat longer than the width of the vehicle body, and at the end adjacent to the ground wheel 13 at the right hand side of the machine as shown in Fig. 1 it carries a small sprocket wheel 33 and a larger sprocket wheel 34, which are preferably made integral with each other, and suitably keyed to said countershaft. It

connection with manure spreaders provided with an auxiliary beater and with a lateral distributor, it is also applicable to manure spreaders not equipped with such elements,

and the term countershaft'as herein used is therefore intended to comprehend either a shaft that extends entirely across the vehicle body, or any sufiicient means for supporting and 'connectingthe sprocket wheels 33, 34 so that they are operativelyr'onnected together and serve as power transmitting devices in the mannerhereinafter described,

At the opposite end of the countershaft26 from that which carries the sprocket wheels 33, 34, it is provided with a cam .36 keyed thereto, (see Fig. 3), by means of which the "feeding mechanism actuated, as will hereinafter described;

.The-sprocket wheel 33, and through it the countershaft 26, isfdriven by a link belt 37 jwhich'travels' around said sprocket wheel @and depends therefrom at th of them;

hiclebody, theflower portion of said" belt being supported fbyla pinion 38, preferably in the form of a small sprocket wheel, which is mounted on a stud 39 carried by one arm I of a lever fulcrumedupon 'apivot'41, so

that it may swing in a vertical plane, and

thereby move the pinion 38 fore "and aft. As

" shown in Fig. 1, the link belt 37 travels around the pinion 38, and consequently by swinging the lever 40. about its pivot the lower end of said belt may be swung fore and aft to move it into or outlof engagement 'with-.=;

the teeth of the driving sprocket wheel 24.

For swinging the'lever, 40 I provide an op.- 7

crating rod 42, the rear'end of which is con nected with'the upper arm of said lever," while the forward: end ofsaid rod is con-1.

nected to a manually operated lever 43 ful- ,7 crumed at 44 adjacent to the drivers seat, so

thatit may conveniently be operated.

; ,The connections between the rod 42"and lever 43 comprise an 'eye'45 projecting lat-i j 1 erally. from the lowerportion of said lever;

1 through which eyethe front end of the rod 42 extends,.{a nd a spring 46 mounted on'said rod d between the eye and a collar 47 secured on said. rod by a cotter pin 48, as" shown in Fig:

1, The spring 46, therefore,'serves as a cushioning 'device' between the lever 43 and the rodf42 v r Itwill be obvious from'an inspection'of 1, so that it swings in a vertical plane. The

lower end of said lever is provided with a side sills 11; Of course, it is to be understood slot 51 whichv receives the stem-of aneye-bolt s opposite sides of said eyebolt the-rod 42 is short distance apart, so thata'litt'le lost mo-q tion is providedbetweenthe lower end of the 53 through which the rod 42 extends. At

provided with adjustable collars 54, 55 set a Lessee? said lever is connected by a link '56 with a fore and aft swinging bar 57 pivoted at its upper end to the side of the vehicle body by a pivot 58, as shown in Fig. 1. The lower end ofsaid bar carries a roller 59 over which the forward courseof the'link belt'37 travels, so that said roller serves as a belt tightener.

It will bev apparent from the foregoing description that longitudinal movement ofthe 1 rod 42m rock the lever'4O will at the same time rock lever 49, and, therefore,.move the roller 59 longitudinally of the machine in conformity with the {0113131116. aft swinging of the belt 37, as clearly indicated by the dotted lines in Fig. 3. Widening ofthe loop 'ofjsaidbelt of course shortens its length, and, therefore, by the' means described said belt is always maintained taut. Also, it will be seen that-swinging of the lever 40 in one di- 1 re' ction 'orthe other will move the belt. 37 into orrout of operative engagement with the drivingsprocket wheel 24. -WVhen saidlbelt is .in

"engagement with the driving sprocket wheel,

the sprocket wheels 33, 34-will be driven con- 26 5, andthrough it the auxiliarybeater 27 and thecam "36 will also-bedrivencontinu- For driving'the-main beater a link belt 60 is provided that travels around-andis driven by the sprocket-wheel34, the lower course of. said-"belt passing under and operatively engaging a 1 sprocket wheel (not shown) which is connected with the main heater 18-. Thus. said beater is continuously j driven from thecountershaft 26 and in the same direction, which direction is opposite to thatinwhich the sprocket wheel 24 and rear" axle 14 rotate In the construction illustrated the machine; is provided with a lateral distributor 61, of the well-known helical type, carried by atransverse shaft 62 provided'with'a sprocket wheel 63, as shown in Fig. 1. The latter sprocket wheel is driven by th'elink belt-6O which travels around the same and over anidler sprocket wheel 64 by whichiits tens-ion i's-iregulated, said sprocket Coming now to, the improvements to which ports 66, 66a'carried by transverse shafts 67, 67a atopposite ends of; the vehicle, so that the tinuously, as distinguished from the inter-" "mittent' driving of the feeding mechanism hereinafter described, and the countershaft 'thepresent.applicationrelates, thebottom of the vehicle :bodyis: formed by an endless 'apron'65' operating-over suitable rotary sup upper course of said apron lies between the that my improvements--are-applicable to that type of manure spreader which is provided with a'solid bottom and having a 'conveyor thetopsur'face of the bottom ofthe vehicle;

explained that the cam 36 carried by the countershaft 26 actuates the feeding mechanism,

and by reference to Fig. 3 it will be seen that V alever 68 is associated with said cam to be rocked fore-and aft thereby about a pivot 69. Said lever is provided with a roller 68a that bears against the periphery of the cam 36, and obviously when said cam rotates in the direction indicated by the arrow in Fig. 3 it will act to swing the upper end of said lever to the left as viewed in said figure. The lower "end of said lever is connected by a link 70 with a radial arm 71 mounted on the shaft 67 a and provided with a pawl 72 adapted to engage the teeth of a ratchet wheel 73 also mounted on said shaft. A detent 74 serves to prevent reverse rotation of said ratchet wheel.

The ratchet wheel 7 3 is loosely mounted on the shaft 67a, and is arranged to be operatively connected therewith by means of an internal gear 7 5 carried by said ratchet wheel and a-spur gear 76 mounted on the eccentric hub 77 of said ratchet wheel, said spur gear being held against rotation by a dog 78 pivotally connected with one of the side sills 11 by a link 79. A device of this character is fully shown and described in Letters Patent No. 1,215,614, to Theophilus Brown, dated February 13, 1917, and, therefore, need not be explained in detail herein. It will suflice to say that as the ratchet wheel 73 is rotated in a clockwise direction as viewed in Fig. 3,

v the upper course of theapron is caused to travel rearwardly. It will be evident that inasmuch as the cam .36 actuates the lever 68. intermittently, the ratchet wheel 73 will be rotated intermittently, and consequently the movement of the apron'is intermittent also. 'As the cam 36 is mounted on the countershaft 26, wheneverthe auxiliary beater is driven the apron 65 will be actuated, but the movement of the beater will be continuous whereas that of the apron will be intermittent, notwithstanding that they are both actuated by said countershaft. It is manifest, also, that the main and auxiliary heaters will both be driven at a higher rate of speed than the apron.

'It is occasionally necessary or desirable to change the rate of travel of the apron, or, inother words, the distance it is moved on each operative stroke'of the lever 67, and my improved construction provides means by which the operator can make such adjustment fifi withoutleaving his seat and also without having to move theload in accomplishing it.

"operated latch 82. The lever 80 is fulcrumed at 83, so that it swings fore and aft, and to it is connected the forward end of a rod 84 which extends back to and a short distance beyond the lever 68, as best shown in Fig. 3. Therear end of said rod is supported by a sleeve 85 which is pivotally connected with the lower portion of the lever 68 by a pivot 86so that it may rock about a transverse axis. Said rod is adapted to slide in said sleeve, and the rear end of said rod carries a fixed stop 87 secured thereto in any suitable way, as by a set screw 88, so that it may be adjusted longitudinally thereof should occasion require. Between the stop 87 and the sleeve 85 is a cushioning spring 89 mounted on the rod 84. The stop 87 is provided with a sleeve 90 that extends toward the lever 68 parallel with the rod 84, which sleeve is adapted to receive a plunger 91'that projects rearwardly from a movable stop 92 fitted loosely on the rod 84 in advance of the sleeve 85, against the forward end of which it bears. The stop 87 is provided with a lug 93, and the stop 92 is provided with a lug 94, as shown in Fig. 3, which lugs are connected by a spring 95 which tends to hold the two stops together, with the plunger 91 incased by the sleeve 90.

It will be seen from the foregoing description that the sleeve 85 connected with the lever 68 is interposed between the stationary stop 87 and the movable stop 92, and that when said lever is given an operative stroke, or, in other words, is swung in a counterclockwise direction as viewed in Fig. 3, and the rod 84 is held against endwise movement by the locking devices associated with the lever 80, as is normally the case, the rearward movement of the lower end of the lever 68 willcompress the spring 89, which will not only cushion it, but after the roller 68a passes off the high part of the cam 36 will restore the lever 68 to its normal position. When the parts are as shown in Fig. 3, the apron 65 will advance the greatest possible distance upon each operative stroke of the lever 68, since the roller 68a is shown as being in engagement with the lowest part of the cam 36, and rotation of the cam will consequently move it the greatest distance that said cam is capable of moving it. By, however, setting the lever 68 so that its normal position when retracted is such that the roller 68a is not in contact with the cam at that time, but is removed therefrom to a greater or less extent, obviouslyrotation of the cam will I sequently the apron 65 will not be moved so fareach time said lever is actuated, a This setting maybe effected by moving the lever '80 rearwardly, thereby moving; the stop 87 reaiwardlfy from-the position shown in Fig.

3, asillustrated in' Fig. 6.- Wh'enthis is done When-this occurs the lever 68 will be rocked bymeans of said cam, thereby movingthe sleeve 85 .backinto engagement with the spring 89 and permitting the movable stop 92toreturn to its normal distance from the fixed stop, 87. After thehigh part of the cam 36Jpasses off of the roller 6806, the spring. 89 will move the lever 68 in the reverse. direction, but its upper end will not cause, owing tothe rearward movement of said rod,-thej position of the stops 92 and 87 V fore, thestop devices as a' whole will tend.

;will have been shifted rearwardly, and, thereto hold the sleeve '85 normally at a point to the 'right of its first position, as indicated by the dottedlines' in Fig. 6. This will Lthrow the roller 68a to the left of the positionshown in Fig. 3, to a greater or less ex,-

" tent, depending on how much of an adjustment has been made,' and, therefore, the next time the cam 36 operates, and in all succeed- .;ing operations thereof until the feeding devices have again been, adjusted, the stroke of the lever 68 effected bytheoperation of said cam will be shortened more orless-in accordance with/the adjustment made. In

other words, theinormal position of the lever 68 with respect to the cam 36 is-varied, with consequent variation in the length'of In mak- "ingythis adjustment the operator does not nipulatesthe stop devices'that control the normal'position of the lever 68, independenthave 1tomove the load, but he merely ma- 1y of the load-,so that-the next time the lever is actuated by the power mechanism, it will return to its new normal position and will continue to use-that position until 'further adjustment'is made by the operator.
